How to make quick 2d animation with blender? Npr
I am not really sure if this will answer your question, but I have done 2D animation before using blender 2.79 and now its much easier now with blender 2.8, because Eevee can render out your project in seconds. 

What I do is that I import the cartoon 2D images as textures on a 2D plane with the same shape of the object or character, and then setup the camera as orthographic to see the plane in 2D, then make a rig for that plane and animate it, after that render it out with eevee, 1 frame renders in less than a second. 

I am explaining all that in a step by step 2 video tutorial you can check it out and see if this method will help you out.
